Question

Help please

Joe drives a 35 M/s for 15 seconds then speeds up to
50 m/s for 50 seconds. How much did Joe accelerate?

Answer 1

We could determine the acceleration using this formula

`\boxed{a= (v_(1)-v_(0))/(t)}`

Joe accelerated from 35 m/s to 50 m/s in 50 seconds, plug in the numbers
a=
`(v_(1)-v_(0))/(t)`
a =
`(50-35)/(50)`
a =
`(15)/(50)`
a = 0.3
The acceleration is 0.3 m/s²
